Multipartite entanglement features of primordial non-gaussianities
Alessio Belfiglio, Roberto Franzosi, Orlando Luongo
We discuss some entanglement features associated with cubic non-Gaussian perturbations in single-field inflationary scenarios. We adopt standard momentum-space techniques to show h…

Geometric multipartite entanglement from gravitational particle production
Alessio Belfiglio, Roberto Franzosi, Orlando Luongo
We explore novel generation of genuine multipartite entanglement within gravitational particle production processes during inflationary stages. To this end, we focus on perturbativ…
